The rms value of current in an ac circuit is 10 A. What is the peak current?
Hence, using the formula,
which is the required value of peak current.
A 44 mH inductor is connected to 220 V, 50 Hz ac supply. Determine the rms value of the current in the circuit.
Inductance, L = 44 mH =
Power consumed = Current x Voltage
= 2.2 x 200
= 484 watt.
Using the relation
